人绒毛膜促性腺激素（HCG）是由合体滋养层细胞分泌的一种糖蛋白激素，它在非滋养叶细胞肿瘤中的出现，已被许多研究所证实[1]。我们通过微粒子捕捉酶免分析法（MEIA）对肺癌病人血清HCG含量的检测，结合病理切片检查分析，发现肺癌病人血清HCG含量对判断癌的组织类型和分化程
Human chorionic gonadotropin (HCG) is a glycoprotein hormone secreted by syncytiotrophoblast cells. Its appearance in non-trophoblast cell tumors has been confirmed by many studies [1]. We detected the serum HCG levels in lung cancer patients by microparticle capture enzyme immunoassay (MEIA), combined with pathological biopsy analysis, and found that serum HCG levels in lung cancer patients determine the type and differentiation of cancer tissues.
